Here's some pics of heavy duty Gatorback mud flaps on mine. I've put them on every van or truck i own. Each one is a little different for mounting depending on size of tires and other accessories like running boards that can help in getting creative for mounting as there is no E series van specific flap available so this is using universal brackets and flaps.
The flaps have cut down on rock chips and mud build up. Im sure there are my flaps that can be used or even make your own brackets but i'll just give you the info on mine and you guys can decide whats best for you. You can check out the flaps and brackets at truckhardware.ca and i believe looking on their site that sharptruck.com carries this brand in the U.S. On the front and back i used the a Gatorback 12" x 23" square style flap and used their universal "L" bracket (

On my bronco i used these (

These required to be drilled into the fender lip but then i ran a support from the frame to the inside corner to help stabilize. Product has all been top notch, again nothing van specific but seems like they have all the tools necessary to put something together to add protection to your van. Hope this helps.
or maybe it's the lift....
